EPISODE DESCRIPTION
Edwin Chen is the founder and CEO of Surge AI, the company that teaches AI what’s good vs. what’s bad, powering frontier labs with elite data, environments, and evaluations. Surge surpassed $1 billion in revenue with under 100 employees last year, completely bootstrapped—the fastest company in history to reach this milestone. Before founding Surge, Edwin was a research scientist at Google, Facebook, and Twitter and studied mathematics, computer science, and linguistics at MIT. *We discuss:*
- How Surge reached over $1 billion in revenue with fewer than 100 people by obsessing over quality
- The story behind how Claude Code got so good at coding and writing
- The problems with AI benchmarks and why they’re pushing AI in the wrong direction
- How RL environments are the next frontier in AI training
- Why Edwin believes we’re still a decade away from AGI
- Why taste and human judgment shape which AI models become industry leaders
- His contrarian approach to company building that rejects Silicon Valley’s “pivot and blitzscale” playbook
- How AI models will become increasingly differentiated based on the values of the companies building them
